You should also restrict access to sambaNTpassword and sambaLMpassword,
but that's a matter for after this is working.

This means that the local unix user (the one with exactly the same name
as the Samba user) does not exist.

Populate LDAP with posixAccount attributes, and configure nss_ldap to
talk to the same ldap server.  This will allow 'getent passwd' to
succeed (showing your samba users), and Samba will then work.

This is now your priority, as it is required to make it work :-)
